DISCHARGE PORT FO'R ICE-CREAM CABINETS.

Application filed December 15, 1922. Serial No. 607,261.

To all whom t may concern:

Be it known that I, CHARLES NELSON, a. citizen of the United States,residing at the city of St. Louis and State of Missouri, have inventednew and useful Improvements in Discharge Ports for Ice-Cream Cabinets,of which the following is a speciication, reference being had to theaccompanying drawings.

My invention relates to discharge ports of ice cabinets and has for itsobject to pro vide a discharge and closed port in relation near thebottom of the ice cabinet, wherefrom the accumulated liquid sedimentscan be fully drained to prevent the overflow 1of the Water and to removeother obstructions.

Another object of my invention is to provide a device of the characterindicated, having novel means for adjusting the sections of the devicein unison froma oentral point, thus making it convenient to shift theparts to suit the requirements as indicated.

Various other objects and advantages will be brought out in thefollowing specific description of the present preferred embodiment ofthis invention, the same being illustrated in the accompanyingdrawingvwherein,

igure 1 is a plan view of the device constructed according to myinvention;

Figure 2 is a longitudinal sectional view of the same on the line 2-2 ofFigure l;

Figure 3 a detached bottom view of the check-arm, and

Figure 4 a vertical section on the line 4-4 of Figure l. v

In the drawing the numeral l represents the section of the side holdingportion of an ice cabinet, having at its intermediate marginal loweredge a central bore 2 to receive a cylindrical stationary member 3.Integral with said member 3 and positioned within the inner surface ofthe frame member l is an abutting nut 4, compr'essively engaging theframe portion 1 by means of the resilient washer 5 and the internallythreaded nut 6. Integral with said nut 6 is a check arm 7 engaging theexternally threaded end portion of the stationary membei' 3 for ahorizontal adjustment with the check arm 7.

The point of termination in the range of movement of the two sections 3and 7 is at the abutting line 8 of the two terminal inner ends of thesections v3 and 7. The check arm 7 is of cylindrical construction, andwhen in composite operation withthe stationary member 3 has its centralbore in aligned relationship with the central bore of the member 3.

Positioned about midway at the bottom of the check arm 7 is a dischargeorifice 9 with a restricted outlet and in co-operative communicationwith the central bore of the stationary member 3. Mounted on theperipheral terminal of the check arm 7 are threaded extensions l0 and llto engage in mesh the threaded components l0 and 11 of the wedge collarl2.

The cup shaped wedge collar l2, concentrically mounted and in embracingrela tion, when in operative engagement with the check arm 7 is fullymovable to assume different relationship to each other and is adapted byits rotational movement, either rearwardly or forwardly to open or closethe discharge port 9, making the two structural sect-ions 7 and l2mutually reciprocable with reference to each other.

It is obvious that the discharge port 9 in operative relation with thewedge collar l2 will allow the accumulated liquid contents in the icecabinet to pass through the restricted outlet 9 and any collective4obstructions from the inner housing of the cabinet l at the mouth of thecentral bore of the stationary member 3 can be removed by manual-meanseither through the discharge port 9 or the open end of the central borein the check arm 7.

Although but one specific embodiment of this invention has been hereinshown and described, it will be understood that numerous details of theconstruction shown may be altered or omitted without departing from thespirit of this invention as defined by the following claims.

That I claim as new is l. In a new article of manufacture, thecombination with a receptacle having an entrance orice therein, astationary carrying member, having one portion adapted to be connectedwith said oriiice in the receptacle, a plurality of interchangeableunits, comprising a series of tubular sections of circularcross-sectional shape in operative engagement and disengagement withsaid carrying member, one of said sections adjacent to the carryingmember having a discharge port for exhausting liquid deposits in saidcabinet therefrom, a Wedge collar in embracing relation With saiddischarge section, means for detachabl-y engaging and disengaging saidWedge collarv and the discharge section.

2. In an ice cabinet, the combination with a receptacle having anentrance orifice therein, a stationary carrying member, rigidly engagingsaid orice in the receptacle in combination with anv operating memberadapted to move into andk out of operative position, comprising a seriesof detachable members, one of said members being in operative alignmentWith said carrying member, motive means carried on said detachablemember, and means for positioning said motive means differentially.

3. In an implement of the class described,

a discharging element, composed of aligned sections, one of saidsections being adapted for insertion into a body portion, fasteningmeans for rigidly holding said section in operative engagement with saidbody portion, an auxiliary member, mounted adjacent and in operativealignment With said section, comprising by means of screw threadedterminals one unit, an outlet port in the bottom of' said auxiliarysection, a skirt element engaging said auxiliary member in open orclosed position.

4. ln a new article of manufacture, the combination with a dischargeelement, an auxiliary member mounted adjacent and in operative alignmentwith saidy discharge element, an outlet in the bottoml osaid auxiliarymember, a skirt element engaging said auxiliary member lin open orclosed position. t

In testimony whereof l hereunto my signature.

CHARLES NELSON.
